Be it known that I, CHARLES D. Mosrrnn, a citizen of the United States,residing at New York city, in the county of New York and State of NewYork, have invented certain new and useful Improvements in Fuel- BurningApparatus, of which the following is a specification, reference beinghad therein to the accompanying drawing.

lily invention relatesto improvements in furnaces, and more particularlyhas reference to means in combination with a furnace for burning liquid,gaseous or dust fuel whereby the proper quantity of air is sup plied atthe proper temperature to insure more perfect combustion, andembodiesvarious other advantages.

Referring to the accompanying drawings, Fig. 1 illustrates in sideelevation, partly broken away and partly in section, an application ofmy invention in which several units are stacked together upon the gratebars of the furnace, Fig. 2 is a modification showing instead of unitsor sections, an integrally formed structure which can beconvenientlyplaced as a whole in position within or removed from thefurnace, Fig. 3 is an enlarged detail in perspective, partly brokenaway, illustrating the units shown in section in Fig. 1, and Fig. 4 isan enlarged perspective view of one of said units in inverted position.

3 is the bridge wall and 4 the base of the furnace, 5 are the usualgrate bars, and 6 the sections, units, or partitions preferably ofcarborundum or other suitable material against the upper edges of whicha suitable jet of liquid, gaseous or other fuel such as 7 may bedirected preferably by a fanshaped nozzle such as 8, or other suitablemeans. 9 indicates the pit below the furnace through which. the air maybe supplied under pressure to pass upwardly through the channels orducts 10 in the units or sections 6.

In. the application of my inventionshow u in Fig. 2 the parts areintended to be formed integrally and the integral structure may beprovided with a lower chamber such as 11 through which the air may besupplied. The fuel from the nozzle 8 which-is preferably constructed todeliver a fan-shaped jet as shown, is directed under pressure so as tostrike the upper edges of the carborundum portions as indicated. As thefuel and air are ignited the contact of the hot gases and radiation ofthe heat upon the carborundum will not be'necessary.

material heat the sameto very high de I gree thereby insuring theheating of the air as it passes through the same, thus creating anintensely hot radiating surface and 1n-' suring a perfect mixture of airas it is projected into the fuel. The form and arrangement of therefractory material is such that it provides ridges or serrations infront of the air channels or ducts thus preventing the flame or gas fromthe burners being projected directly into the air ducts. The position ofthe burner is preferably low so as to direct the gas or flamesufficiently nearly horizontal to strike the ridges, corrugations orserrations instead of entering the air inlet passages.

Where the sections or units are stacked as indicated in Fig. l, the samemay of course be supported by the grate bars as shown, but where thesame are intended to be formed integrally in a single structure as shownin Fig. 2 the entire structure may be readily. fitted in place, and ofcourse the grate bars neath the combustion chamber it will. be ob servedflows upwardly and according to the construction shown in Fig. 2 is thencaused to be delivered into the furnace in the reverse direction to theinflowing fuel which strikes it above the air outlets and instantly andintimately mixes with the air driving the products of combustionrearwardly over the bridge wall. In the form shown in Fig.

1 suitable blocks or slabs of refractory material preferably ofrectangular formation except that the lower ends of the same may The airadmitted he I be beveled or cut at an ngle to rest upon the gratebars,'may be stacked, said blocks or slabs being provided upon the undersurface with suitable grooves or channels serving as ducts through whichthe air may be drawn. The fuel being injected under pressure in afanlike stream over the top edges induces the air to pass upwardlythrough the ducts or channels where it is met by the fuel, thoroughlymixed therewith and ignites with it. It is of course preferable tosupply the air under pressure, the same entering by the inlet 12 andpassing upwardly through the ducts where it meets the incoming fuel asaforesaid, although the air need not be supplied under pressure. It willof course alsobe readily understood that the burner may be placed in thefurnace shown in Fig. 1 so as to oppose the airentering the. passages 10as shown in Fig. 2, but where the fuel and air are opposed in thismanner it is of course preferable to supply the air under forced draft.

Of course it will be understood that va rious modifications may he madein the construction and arrangement of parts with out departing from thespirit of the invention as claimed.

I claim:

1.In combination with afurnaca. bricks of refractory material arrangedin parallel rows transversely of the furnace and fornr ing substantiallystraight passages between said bricks extending entirely from end to endof the same for admitting air, and means CHARLES n. MOSHER.
